GENERAL
The MSP2020 belongs to a full family of
Multi-Service Processors designed to
meet the performance, QoS and security
needs of communications equipment
used within the customer premise. The
MSP2020 is an ideal solution for VoIP
Gateways and Secure Wired and
Wireless IP Phones. As shown below, it
includes a MIPS CPU, three 10/100
Ethernet MACs, TDM interface, PCI
interface, and a security engine.
The MSP2020 provides a new level of
price performance for VoIP Gateways,
and Secure Wired and Wireless IP
Phones. Because the MSP2020 elimi-
nates the need for a separate processor,
voice processing DSP, security chip and
multiple Ethernet MACs, systems can
now be built with fewer chips at a very
affordable price point.
The MSP2020 has a unique systems
architecture that provides wire-speed
performance. This architecture includes
a powerful MIPS CPU, a 4.25 Gbps bus,
16KB Scratchpad, and intelligent context
aware DMA engines. Together, this
results in an extremely cost effective
VoIP solution that includes security.
Integration of 802.11a, b, and g wireless
LANs is easily facilitated through the
PCI interface.
To reduce time-to-market, PMC-Sierra
offers comprehensive support for the
MSP2020, including evaluation boards,
software, application engineering
support, training, and documentation
that together accelerate the product
development process. In addition, the
MSP2020 supports Linux, VxWorks, or
custom operating systems.
